概要
説明
The ISL70001SRHEVAL1Z evaluation board is designed to demonstrate the features of the ISL70001SRH, a TID and SEE hardened 6A synchronous buck regulator IC with integrated MOSFETs intended for space applications.
The ISL70001SRHEVAL1Z evaluation board accepts a nominal 3V to 5.5V input voltage and provides a regulated output voltage ranging from 0.8V to 85% of the input voltage at output currents ranging from 0A to 6A. The output can be quickly set to any of six commonly used preset voltages (0.8V, 1.0V, 1.2V, 1.8V, 2.5V, 3.3V) or adjusted to an alternate voltage using the onboard potentiometer. A power-good (PGOOD) signal goes high and lights a red LED to indicate that the output voltage is within a ±11% typical regulation window. A toggle switch is provided to conveniently enable or disable the output voltage.
The ISL70001SRHEVAL1Z evaluation board can be set to run from the nominal 1MHz internal oscillator of the ISL70001SRH or synchronized to a 1MHz ±20% external clock. Two or more ISL70001SRHEVAL1Z evaluation boards can be synchronized to each other in a Master/Slave configuration, with all Slave units switching 180° out-of-phase with respect to the Master unit.

Hello, my name is Josh Broline, product marketing manager for Intersil space and high reliablilty products. Here at APEC 2012, I am demonstrating the industry's only monolithic power solution for FPGA power.
See here, on this eval board, we have three space grade power solutions. The ISL70001, which is a 6A voltage regulator with integrated FETS. The ISL70002, a 12A solution, and the ISL75051, an ultra-low LDO.
Now, these are all specifically designed for space level environment. For more information on our fully monolithic power solution for FPGA, go to our website. There, you can find Gerber files and schematics for this reference design.
